PDF-Eddy current sensors for displacement distance and position Noncontact eddy current sensors

A high frequency alternating current is fed through a coil embedded in a sensor housing The electromagnetic field from the coil induces eddy currents in the conductive target As a consequence the alternating current resistance of the coil changes Th. The Kemet Flatness Gauge is used to monitor a lapping plate’s flatness and to give an indication of the flatness the plate will produce on a given part size. The Gauge comes with a calibrated do Control after receipt. 1. /11. Sylvain GRIFFET, 13/12/2010. Measurements performed on the 29st of November 2010 with the Laser Tracker LTD500. EDMS n°1108177.

Eddy current inspection is one of several NDT methods that use the principal of “electromagnetism” as the basis for conducting examinations. .. Eddy currents are created through a process called electromagnetic induction. When alternating current is applied to the conductor, such as copper wire, a magnetic field develops in and around the conductor. This magnetic field expands as the alternating current rises to maximum and collapses as the current is reduced to zero. If another electrical conductor is brought into the close proximity to this changing magnetic field, current will be induced in this second conductor. Eddy currents are induced electrical currents that flow in a circular path. They get their name from “eddies” that are formed when a liquid or gas flows in a circular path around obstacles when conditions are right.. is a . sensor.  able to detect the presence of nearby objects without any physical contact..
